I have all these symptoms too... the heart palpitations, sweating, flushing, feeling extra emotional. My coworker said something to me that normally would not upset me and I started to have tears in my eyes and I couldn't help it at all I had to walk away. I thought it was probably all due to my anxiety but I've never experienced it like this before. I got 8 trigger point injections in my thoracic area on Friday, so it's almost been a week for me now. I am also wondering when my back pain should feel better?? My doctor also never told me any of this, I can't believe how common it seems to be!!
Corticosteroids have been used as drug treatment for some time. Lewis Sarett of Merck & Co. was the first to synthesize cortisone, using a complicated 36-step process that started with deoxycholic acid, which was extracted from ox bile .  The low efficiency of converting deoxycholic acid into cortisone led to a cost of US $200 per gram. Russell Marker , at Syntex , discovered a much cheaper and more convenient starting material, diosgenin from wild Mexican yams . His conversion of diosgenin into progesterone by a four-step process now known as Marker degradation was an important step in mass production of all steroidal hormones, including cortisone and chemicals used in hormonal contraception .  In 1952, . Peterson and . Murray of Upjohn developed a process that used Rhizopus mold to oxidize progesterone into a compound that was readily converted to cortisone.  The ability to cheaply synthesize large quantities of cortisone from the diosgenin in yams resulted in a rapid drop in price to US $6 per gram, falling to $ per gram by 1980. Percy Julian's research also aided progress in the field.  The exact nature of cortisone's anti-inflammatory action remained a mystery for years after, however, until the leukocyte adhesion cascade and the role of phospholipase A2 in the production of prostaglandins and leukotrienes was fully understood in the early 1980s.
For years I have had barometric pressure migraines with related ear pain. My belief is that the extreme muscle tension from fibromyalgia and ME cause both the inner ear issue and the migraines. When everything–muscles, tendons, fascia–is already tight, the slightest environmental changes can cause pain. In fact, fatigue is listed as one of the causes of patulous eustachian tubes. Take TMJ (please!), a comorbidity of fibromyalgia; if muscle tension can affect the jaw enough to displace it, it follows that extreme muscle tension also affects the ears and eyes. My vision is impacted by fibro, too, particularly in the left eye. I know this is a result of muscle tension because I can manipulate the muscle of my left eye with my hand and actually improve my vision. If it were a lens issue, this improvement would not be possible. Again, a small experiment that no ophthalmologist would believe or even try.
